1800-2000MHZ UHF Band RF Coaxial Wehewehe
He aha te mea he wehewehe?
Kaiwhakawehe RFhe taputapu kore-whakamātautau ferromagnetic rua-awa, e whakamahia ana hei tiaki i ētahi atu wāhanga RF mai i te pakaru o te whakaata tohu kaha rawa. He mea noa ngā taputapu wehewehe i roto i ngā tono taiwhanga, ā, ka taea te wehewehe i ngā taputapu kei raro i te whakamātautau (DUT) mai i ngā pūtake tohu tairongo.
Te tono hua
• Whakamātautau taiwhanga (ultra-bandwidth)
• Whakawhitiwhiti kōrero amiorangi
• Pūnaha ahokore

Te Tuhi Whakatakotoranga
Te rerekētanga i waenga i te isolator me te circulator
He taputapu maha-awa te porowhita e tuku ana i te ngaru taunga e tomo ana ki tētahi awa ki te awa e whai ake nei, e ai ki te ahunga i whakatauhia e te papa aukume pūmau. Ko te āhuatanga matua ko te tuku pūngao kotahi-ara, e whakahaere ana i te tuku o ngā ngaru hikohiko i te ahunga porowhita.
Hei tauira, i roto i te porohita i te ahua i raro nei, ka taea anake te tohu mai i te tauranga 1 ki te tauranga 2, mai i te tauranga 2 ki te tauranga 3, me te tauranga 3 ki te tauranga 1, ā, kua āraia ētahi atu ara (he nui te wehenga)
Ko te tikanga, ko te wehewehe he mea hanga i runga i te hanganga o te porowhita. Ko te rerekētanga anake ko te wehewehe he taputapu tauranga rua, e hono ana i ngā tauranga e toru o te porowhita ki te kawenga taurite, ki te ara iahiko kimi rānei. Nō reira, ka hangaia he mahi pēnei: ka taea anake te haere o te tohu mai i te tauranga 1 ki te tauranga 2, engari kāore e taea te hoki ki te tauranga 1 mai i te tauranga 2, arā, ka tutuki te haere tonu o te huarahi kotahi.
Mena ka honoa te tauranga-3 ki te pūoko, ka taea hoki te kite i te kore taurite o te taputapu taunga e whakamutua ana e te tauranga-2, ā, ka taea hoki te kite i te mahi aroturuki ngaru tū.
